Works between sessions.
Approved emails send on schedule and replies are collected while your agent is offline.
Connect your AI agent to real outreach.
Sellbird connects to the AI agent you already use through MCP, the open standard for agent tools. Your agent finds buyers, writes the emails and drafts the replies. Sellbird gives it the contacts, campaigns, inboxes and conversations to work with, with draft approval on by default.

It does the work. You make the calls. You keep the decisions that cost money or reach people.
The line is drawn in the server, not in a prompt. Tools that would send, spend or change something you own create a request instead, and the dashboard shows it with a button only you can press.
Every campaign email waits for your approval by default. A workspace owner can turn on autopilot in settings, and then campaign emails send without one-by-one approval, still inside your sending limits and opt-out rules. Reply drafts always need your approval. Your agent can never turn on autopilot, approve a draft or approve a purchase.
Your agent can
- Read your setup, contacts, campaigns, conversations, inbox health and spend
- Import contacts and build cohorts from buying signals
- Create campaigns and write or edit every draft
- Draft replies to the people who wrote back
- Ask for domains, inboxes and warmup, and pause sending
Only you can
- Approve an email in the Outbox
- Buy a domain or add an inbox that raises your bill
- Change DNS on a domain you brought
- Confirm a signal or start a paid discovery run
- Raise a daily cap, or resume sending after a pause
Signed in, scoped, revocable.
Each agent signs in with OAuth, works within your workspace access and can be disconnected on the Agents page.
Limits per connection.
Each connection has its own rate limits, and one switch stops every agent in a workspace at once.
Agents,
answered.
What is MCP?
MCP (Model Context Protocol) is the open standard AI agents use to work with outside tools. Sellbird runs an MCP server, so once your agent signs in it can use Sellbird’s tools in the workspace you allow, the same way it uses files or a browser.
Which AI agents work with Sellbird?
Sellbird works with any client that supports remote MCP with OAuth sign-in, such as Claude, Claude Code, ChatGPT, Codex and Cursor. Copy the MCP address from the Agents page in your account and add it to your client. Support depends on the client’s version, plan and admin settings.
Does my agent have to stay connected for emails to send?
No. Your agent prepares the work during a session: contacts, campaigns and drafts. Sellbird sends what you approved on schedule and collects replies around the clock. They are waiting the next time your agent connects.
Can my agent send email without me?
Not unless you allow it. Every campaign email waits for your approval by default. A workspace owner can turn on autopilot in settings, and then campaign emails send without one-by-one approval, still inside your sending limits and opt-out rules. Reply drafts always need your approval. Your agent can never turn on autopilot, approve a draft or approve a purchase.
How do I disconnect an agent?
Revoke it on the Agents page, or pause agent access for the whole workspace. Emails already scheduled are separate, so pause sending too if you want those to stop.
Give your agent somewhere to send from.
Request early access. When your spot opens, connecting your agent takes a couple of minutes.
